Default What is this bug?

I am pretty sure I'm going to feel foolish when I find out what I saw. It's gonna be obvious.

I already feel foolish because I didn't snap a pick of it. It had a very simple design however so I will give description a chance:

Went fishing today and, as I normally do I looked between and under rocks etc. to see what was going on. I saw a bunch of Baetis and some black stoneflies darkening up.

Then I saw, underneath about every other fist sized rock, what looks like a featureless caterpillar or grub. Dark brown stripe down the back light gray besides. Legs very much like a caterpillar. Obvious meaty sectioning from head to butt. no characteristic stonefly antennae tail etc. very fat, probably 1 and 1/2 inch in length. The butt end has a very stubby fibered tail darker than the brown back strip.

Tries to curl into a ball and stay still when you mess with it. Once relaxed it straightens out and works it's way back under rocks.

I feel like I do when I can't think of a popular actor's name. I know this bug and I'm gonna tie some up regardless as I'm sure trout can't resist a giant squishy meal like this when they come across it.

Other than coloration, did it look anything like this?

Cranefly!! Not sure if this is the exact species as the ones I saw were better contrasted the top of the worm being darker brown, with the faint white lines Which I assume are innards or whatever.

I thought cranefly initially but I did not, for some reason, expect them to be so big and indeed so abundant. There were plenty of these things around although they were pretty well hidden. their defense mechaism of haphazardly bending into a grubby croissant must work against them when trapped in current as they seemingly will tumble about in a crescent until current subsides and they are able to retreat into cover?

I think a size 4 or 6 caddis worm hook? favorite cranefly patterns anyone?

Craneflies are true flies and in the same family as midges, Dipthera. Here are three patterns for the larva:

From reading about adult cranefly patterns, the best dry pattern seems to be "Brun's Tipula" by Norwegian Andre Brun. It was in FFM in 2002. It is a relatively easy fly to tie and looks fantastic. I would use the correct brown color of foam rather than coloring the foam.

On the mad river in Ohio I fish size 6 crane fly patterns all winter long for Big Browns. I take lead wire and wrap 1/2 the shank in the middle. the wrap in some brassie sizes copper or brown wire to the back. Next wrap some tan dubbing with a little sparkle in it very thick up the hook. and finish by wrapping the wire forward! Its a killer pattern for big fish with the larva in em.

Yeah...I think I'd opt out of that too!

That is one creepy insect. I can remember fishing with hellgrammites as a kid, we could buy them in a bait shop, I do not recall ever seeing one of these adult dobsonflies with the huge pinchers.
